Validation of the Dyslexic Reading Hypothesis: The Staten Island Study

  • Harold N. Levinson


According to the dyslexic reading hypothesis, dyslexic individuals scrambled letters and words because of the presence of a subclinical nystagmus and a related ocular fixation/sequential tracking dysfunction. As a result of this hypothesis, the author postulated that upon optokinetic testing, dyslexics would manifest a statistically significant reduction in tracking capacity when compared to normal controls. The purpose of this study was to measure the c-v-induced ocular fixation and sequential scanning functions in both c-v dyslexic and normal control groups—and thus test the validity of this reading hypothesis.
